My proposal is suitable for this project

• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Description

What:
Adds experimentalDecorators option to @typescript-eslint/typescript-estree.
It just corresponds to experimentalDecorators in TS compiler options.

Why:
Since TypeScript 5.0, ECMAScript decorators are implemented; we can switch between them using experimantalDecortors in the compiler options.

There is no way to switch it on in typescript-estree except by specifying tsconfig.json by project.

It would be helpful to have experimentalDecorators as a parsing option, like the already existing jsx option.

Fail

// N/A

Pass

// N/A

Additional Info

I think we can avoid breaking changes by setting the default value of this option to true. (And, we can change it to false at next major version)
